ADJUSTABLE OPTICAL LENS

摘要

This disclosure includes an adjustable optical lens comprising a membrane (103), a support (101) for the membrane (103), a fluid (102) between the membrane (103) and the support (101), and an actuator for deforming the membrane (103). The actuator comprises a first electrode (104) interconnected to the membrane (103), and a second electrode (106). The second electrode (106) is arranged above the membrane (103) such that the first electrode (104) is arranged between the support (103) and the second electrode (106). As a result, the lens can deform from convex to concave. Furthermore, no fluid (102) can be enclosed in between the electrodes (104, 106) and therefore, no variation of the thickness of an insulation layer between the electrodes (104, 106) can occur due to fluid enclosure resulting in a not precise actuation and consequently deviations from the desired optical properties of the optical system in question. By segmenting the second electrode into high and low conducting sections, the center of the lens can be moved in lateral direction by applying different voltages to the segments.
